Runtime schema validation

Added

Before: Runtime schema validation did not exist
After: Actors validate schemas at runtime

Applications can install a Standard Schema validator on machines and actor logic. It rejects invalid inputs, events, results, outputs and emitted events with structured errors; the build-size benchmark includes a validated machine.

In favour

In favour: Structured errors identify the failed boundary, actor, event, and schema issues
In favour: Validation remains optional for actor logic without validator configuration

Against

Against: Enabled validators run for every input, event, and transition result
